(Cl. 198-134) This invention relates to an improvement in identical and which travel on opposite sides of driers for photographic stills. It may also be the cabinet adjacentto the inner walls thereused for drying other objects or materials which of. i The direction of this travel is indicated by are in theform of stifi sheets, or which may be the arrow '18 in Fig. 1.

The invention consists primarily of a long horiternating in the manner indicated inthe drawzontal cabinet through which air, which has been" ings, Fig. 3; the links of each chain being tied previously conditioned as to temperature and by. rods-21 which extend across the cabinet, and humidity, is circulated; and in which cabinet is which support the wire trays 40 hereinafter rean endless conveyor embodying a novel tray conferred to. 65 4 struction whereby photographs, mounted on fer- Roller bearings 22 are freely mounted on the rotypes, may be carried in oblique position to inrods 21 and serve the double'purpose of separatcrease the eifectiveness of the drying air, and ing the plates which make up the chain links, and contribute to economy of space. providing a bearing surface for supporting the g Fig. 1 is a side view in section of the entire chainin its course of travel. 70 drier.

Between these sprocket conveyor which has an endless chain device and wheels 25 and 26 the roller bearings 22 travel on 75" attached wire trays. horizontal tracks 27 and 28, 29 and 30, which Fig. 4 is an enlarged fragmentary view of a are made up of angle irons extending longitubaflie adjustment which controls the volume of dinally along the inner walls of the cabinet 1. air admitted at diiierent points of the drying The chains 16 and 17 are moved in synchronism u chamber. by two of the sprocket wheels 26, one at each side so 1 Objects and advantages of the invention will of the cabinet, wh ch a o at d y an 8180- be made apparent in the description of the matric motor 31 transmitting power through a chine.

The wire of each tray is bent locked in any desired position by thumb screw 13. sothat short ends 43 and 44 of wires 41 and 42 Arranged to travel horizontally lengthwise of respectively extend from the rod 21' on which the cabinet 1, is an endless carrier 15. This is they are mounted, back to the last succeeding rod 55 made up of two chains 16 and 1'7, which are 21, on which they rest, one above and. one below, V

in such a manner that the rod may rotate between them. The two sections 43 and 44 are welded to a cross wire 45 as indicated in Fig. 3 and thus form the lower edge of the tray upon which the ferrotype may be supported.

It is necessary to have the extreme end of the short sections 43 and 44 engage the last succeeding rod 21 freely because of the rotation occurring when theendless chain curves around the sprocket wheels 25 and 26.

Links 50 connect each of the rods 21 at the center thereof, for imparting rigidity to the structure.

places the ferrotypes carrying the photographs on the trays one after another in the manner indicated in Figs. 1 and 3. The particular machine illustrated has two trays on each rod 21.

Air is circulated through the drying chamber as heretofore described, that is, in the direction opposite to the travel of the photographs, and in so doing dries the photographs.

As the photographs reach the delivery end 4 of the drier, the trays in descending around the sprocket wheels 26 tip over so that the ferrotypes slide off the trays and on to the inclined belts 35. By these belts, the ferrotypes, carrying the photographs on their upper surfaces, are delivered to a shelf 58, where an operator strips the photographs from the ferrotypes.

Having described my invention, I claim as new and patentable:

In a drier for photographs and the like, a carrier comprising: apair of endless chains; two pairs of sprocket wheels arranged to support and drive the chains in parallel paths; a plurality of supporting rods extending from one chain to the other and forming supports for trays; and a plurality of trays secured to the supporting rods, each of said trays comprising a wire wrapped around the supporting rod and having a short end extending back to rest on the last succeeding rod, another wire wrapped around the supporting rod and having a short end extending back to rest on the opposite face of the last succeeding AUGUST EMIL MUTSCHER.
